As I mentioned on another thread, I have been testing a profile created by S3D for the QuickFill head. I have made some basic changes myself to speeds/temps but I won’t have the time to work to properly with this to take it further. So S3D have said it was ok to post the profile here (attached) so if anyone is interested it can develop much quicker. I believe S3D will come along at some point to help too.
*** VERY IMPORTANT ***
This is a development profile and S3d cannot guarantee that it will work correctly with all aspects of the software just yet. Also, more importantly, I imagine this might have an effect on any Robox warranties. Please only use this if you understand what you are doing particularly with S3D.STEELMANS 3D PRINT.

Website: www.steelmans3d.comI tweaked the first Replicator 2 profiles in Simplify3D until they worked properly for PLA, ABS and Nylon some years ago and published them on Thingiverse. The Replicators also use a postprocessor to convert gcode to x3g. It was a team effort to get all the pieces together and provide a seamless toolchain with a powerful slicer for the Replicators.
On the Robox the dual material head with the needle valves is the most interesting feature. I appreciate that a team is working on replacing the outdated cura slicer in Automaker with a current version of slic3r. If you are interested I would work with you on the Robox profiles for Simplify3D. Do you have a Robox Dual? My Robox has been upgraded to a Dual and I frequently have to use Polysupport. Therefore I would prefer to dial in the S3D profiles for the dual material head first.
@enginwiz Thanks for the reply. I started editing the profile for the Dual using PolySupport in one extruder. Unfortunately I don’t think I can put the time in, hence posting it on here.
Also although S3D is great for printers like the Cubicon it just doesn’t work well for the Robox. Don’’t get me wrong the print quality is good and it gives great control over support etc. but it falls down is the exact areas that make AM so good.
The whole workflow, purge process, calibration etc that is smooth in AM can’t be replicated in S3D. Actually S3D is a pleasure to use with my other printers but on the Robox is just seems clunky. I understand this profile is developmental but it is impossible to compete with AM for usability on the Robox.
Although it doesn’t really suit me I know many users have been asking for an S3D profile for a while.

Website: www.steelmans3d.comI really like Automaker. CEL did a great job in implementing all the service tools in Automaker. Root is another example of their capability. But the old cura in Automaker and the missing preview are severe limitations for the users.
Makerbot screwed up during the development of Makerware and left us with a half-baked slicer that had more bugs than working features. It took several people in the Makerbot community about two years to set up a reliable software toolchain that allowed us to use Kisslicer, Simplify3D, Slic3r and Cura as slicers for the Replicator 1 and 2. Still today we use a special version of ReplicatorG to change firmware settings or update the firmware. The control panel in Simplify3D initially didn’t work for the Replicators and today still provides only basic features.
My time and my programming skills are limited. But I think that the Robox deserves a state-of-the-art slicer and a preview and I am offering to contribute some of my free time to the Simplify3D profiles. The question is wether we should open up an additional thread in the Simplify3D forum to raise a team that is contibuting to this project.
@enginwiz I’ve given S3D the link to this thread and they are coming here (I hope!)

Website: www.steelmans3d.comI have a robox with the quick fill head and access to Simplify3D through work. I’ll give this a try.
I found this post in the user forum of Simplify3D
https://forum.simplify3d.com/viewtopic.php?f=23&t=1486&p=5549&hilit=Robox#p5549
It looks like CEL asked Simplify3D for supporting the Robox in 2014.
The post contains a detailled description of the special gcodes used by the Robox.
Two years ago the programmers of Simplify3D managed to reverse engineer the closed source control language of the crappy 5th Gen Replicators and came up with a postprocessor to run these machines from S3D. This was way more complicated than integrating the special gcodes of the Robox.
I would appreciate a collaboration between CEL and Simplify3D for the slicing profiles. In the past I was a beta tester for version 2 of Simplify3D on the Replicator 2. I can offer to do some beta testing on the Robox Dual.
I imported the fff for the Quickfil printhead into Simplify3D 3.1.1.
Start and end gcode for the Robox look good, the setup for build plate size, origin and axes are OK.
What I don’t like in your fff is Auto Extrusion Width for the nozzles. We had that initially in S3Ds first fff for the Replicator 2 and it gave us nothing but trouble. I recalibrated the Extrusion Factor for a fixed Extrusion width matching the real nozzle size and that led to the first stable fff for the Replicators in 2013.
Therefore I want to recalibrate your fff for the Robox Quickfil head also to a fixed extrusion width. Preferably with the actual filament diameter of the Robox PLA.
This will take some time. I didn’t print with the Quickfil head and PLA for a quite a while. Somewhere I should have a roll of white Robox PLA on a smartreel. To make sure that the Quickfil head and the white PLA perform flawlessly I need to print a number of calibration parts with Automaker 3.0.0.
Then I will print 10 x 10 x 10 mm calibration cubes with 100% infill with both nozzles from S3D at fixed extrusion width to dial in the extrusion factor. Afterwards I want do dial in retraction. The 4 mm in your fff are very high. I don’t want to pull PLA back into the cold zone of the print head during retraction and get a cold plug.
First results:
My reference prints with PLA and the Quickfill head in Automaker 3.0.0 are on the green sheet.
The first prints with gcode from Simplify3D 3.1.1 are on the pink sheet. A retraction of 1 mm is sufficent. There is no visible stringing during printing with the 0,3 mm nozzle. I turned off all the fancy stuff like coasting, wipe and extra restart distance. This actually improved the print quality in the upper region of the deprime test.
Workflow: Gcode from Simplify3D is saved to a file on the host computer. In Automaker 3.0.0 I go to Settings (the coged wheel icon), then to maintenance. There is a button to send and execute gcode. I select the file that was created by Simplify3D and Automaker sends it via Root to the Robox and starts the print.
Three larger pictures of the prints on the pink sheet.
Solid 10 x 10 x 10 mm cube, with a bit of underextrusion
Deprime test, with and without coasting, wipe and extra restart distance.
@enginwiz if that’s your workflow - then it is worth trying to incorporate it to what @nebbian did here http://www.cel-robox.com/forums/topic/using-another-slicing/page/6/#post-39666
It would be a benefit to use multiple slicers with the Robox. Simplify3D is just one slicer of many. They all have their pros and cons.
I appreciate your effort to integrate Slic3r into the native workflow of Automaker. This is more elegant than my simple approach of sending gcode files to the Robox via Automaker.
Currently my Robox is printing your torture test with the 0,3 mm nozzle. I added a small negative extra restart distance of 0,2 mm in Simplify3D to prevent blobs at the start of a new perimeter. With a little bit of luck can post a picture of the printed part in about an hour.
